Like much of the stuff here.
The Haunt Shift "immortality" trick doesn't really convince me for instance.
SorO_Lost, I loved the Hindsight trick !
Did you come up with it ?
Tleilaxu_Ghola made some cool contributions to time-traveling with his Terminator build (meant to end Pun-Pun).
I have a fondness for
Body Outside Body (Wu Jen spell, CA) personally.
The basic idea is to get BoB as a SLA so that the clones can cast it too (they can't cast spells... but SLAs are not mentioned - and they will be obtained via class features which are explicitly retained).
That means Archmage for an arcane caster or Hierophant for a divine caster (who'd use Miracle).
So: you have infinite clones in 1 round (the clones act right after being created). Now find them something useful to do:
- clone bombs. Get Death Throes as a SLA, the clones cast it on themselves and one sets off the chain reaction...
- combat clones. Get Giant Size, Shapechange and/or Transcend Mortality as SLAs. Even with mediocre BAB your army will tear down mountains.
- get infinite X. It can be Incantatrix metamagicking of others' spells, Turn Attempts (with the Hierophant ability), actions (this one's trickier, but Cleric into RKV with White Raven Tactics does it), etc...
Just pick a class feature or a combination of a few abilities and imagine an army that has those...
Once I imagined just using it to find someone: you let your clones replicate until they fill the planet you're on and find the target. Then they report his location back to you. It doesn't work with infinite planes unfortunately.
